DESCRIPTION
The Nova 541 Series chlorine alarm monitors are designed for the continuous detection of Cl2 in ambient air.
The Cl2 sensor is capable of excursions over 100 PPM with no damage. The Cl2 sensor is a disposable
electrochemical type with an expected life of between 3-4 years. The sensor needs no warm-up time and is
ready to go as soon as the monitor is turned on. Several versions are available as shown below.
